Beit known that we,- GEoRGii A. Emmand HERBERT D. TRAUB, both citizens ofthe United States, and residents ofDefiance; in

thecounty of-Defiance and 'St'ateof Ohio, have invented a new and Improved Wheel Rim Equalizing and Joint l orining-lVlaQ chine, of which the following is-a full clea-r,"

andexactdescription. i i

The invention relates to Woodworking machines fand its object is to provide anew' and improved wheel rim equalizing and joint forming machine"arrangedfor cutting oil theends of an approximately semicircular wheel rim s'tocktoreduce thelatterto a true semicircular(shape"and t'ofform joints :on

the ends of the stock to -permit of joining tworim sections in an accurate manner. An-

other object is to form-'tlie tongues of the joining ine mbersat one end the settlicircular rim section in alternate relation with the tonguesat" the other endof the rim j.

of the rim; e A A A V In' order to accomplish the desired result use is made of a" circular saw, a'revoluble cfutter head to, one side of the said circular saw a-nd havingits axis'ata right angle to adapted to hold the wheel rim' section and mounted to travel sidewise in front of the saidzcircular' saw andfthe said cutterhea'd t0 successi'vely, cut; oil the endsof the wheel" is also made of" means for supporting a Wheel rin 'section in a t-iltedposition'inthe carriage so that the cutter head provides the ends of the rim section' witlitongue's of which the'tong'ues inone' end are inalteri-i nate, relation' with 1 the tongues at the other end OfthIlIH section. 1
